The CGX 11” RASA telescope is an excellent advanced-level imaging setup. The Rowe-Ackermann Schmidt Astrograph (RASA) produces images in a fraction of the time compared to other optical tubes. The CGX mount provides superior performance for larger telescopes while taking advantage of Celestron’s most advanced technologies: All-Star Polar Alignment, Celestron PWI telescope control software, Starry Night Special Edition software, SkyAlign, and permanently programmable periodic error correction (PPEC).\u003c\/p\u003e\n\u003cp\u003eIf you’re an experienced imager, you’ll love taking this portable mount to a dark sky site and enjoying all the conveniences of a larger observatory mount.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRowe-Ackermann Schmidt Astrograph Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCapturing impressive deep-sky astroimages is easier than ever with Celestron’s Rowe-Ackermann Schmidt Astrograph (RASA) V2, the perfect companion to today’s top DSLR or astronomical CCD cameras. This fast, wide-field f\/2.2 system allows for shorter exposure times compared to traditional f\/10 astroimaging, without sacrificing resolution. Because shorter sub-exposure times are possible, your equatorial mount won’t need to accurately track over extended periods. The short focal length also lessens equatorial tracking demands. In many cases, autoguiding will not be required.\u003c\/p\u003e\n\u003cp\u003eRASA 11 V2 builds on the legacy of Celestron’s Schmidt Cameras, which allowed astrophotographers to produce images with much shorter exposure times on film in the 1970s.\u003c\/p\u003e\n\u003cp\u003eToday, with CCD sensor sizes as large as film or larger, the RASA 11 V2 offers a 43.3mm optimized image circle to capture pinpoint stars on the largest imaging chips. Optical performance for huge sensors with diagonals of up to 52mm wide is still excellent.\u003c\/p\u003e\n\u003cp\u003eCombine this large image circle with a focal length of just 620mm and you have an instrument suitable for wide-field imaging, creating huge mosaics of the night sky, surveying, and even comet hunting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOptical Performance\u003c\/strong\u003e\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003eThe RASA 11 V2 features optics with 4-element rare-earth glass for images free of false color and aberrations like coma and field curvature. The optical quality and spot size across the entire image circle are unprecedented for an astrograph in this price range—or even that of a much more expensive instrument. The design also provides minimal vignetting.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAdvanced Features\u003c\/strong\u003e\u003cstrong\u003e\u003cbr\u003e\u003c\/strong\u003eRASA 11 V2 utilizes the new Ultra-Stable Focus System (USFS). At the heart of this system is a precision linear ball bearing. The bearing serves to minimize focus shift (unwanted lateral motion of the primary mirror during focusing which causes shifting of the image) and mirror flop (movement of the primary mirror when the telescope is pointing to different positions in the sky). The USFS is also compatible with the optional Celestron Focus Motor (#94155-A). The integrated 12V DC MagLev fan reduces cooldown time and provides optimal airflow through the dust filtered optical tube.\u003c\/p\u003e\n\u003cp\u003eEngineered as a complete astroimaging system, every component of the RASA 11 V2 is optimized for peak performance with DSLR and astronomical CCD cameras. Down to the thickness of the glass used in the included fully-multicoated optical window or optional imaging filter, every component of the system has been taken into careful consideration to work together seamlessly. The Dovetail CGE bars on the top of the optical tube provides a connection for use of optional accessories like a guidescope.\u003c\/p\u003e\n\u003ch4\u003e\u003cbr\u003e\u003c\/h4\u003e\n\u003ch4\u003eCGX Mount\u003c\/h4\u003e\n\u003cp\u003eCelestron’s engineering team applied their years of experience designing German equatorial mounts to CGX, a culmination of all Celestron’s advancements in technology, value, and ease-of-use. Capable of carrying the RASA 11 with ease, the CGX is perfect for backyard and remote imagers looking for exceptional load capacity to weight ratio, compact design, and innovative features that fully support advanced telescopes, imaging kits, and the latest in wireless tech accessories.\u003c\/p\u003e\n\u003cp\u003eCGX was designed to better support your telescope for both visual and astroimaging pursuits.
